silentbrad writes: The biggest danger facing the success of Steam Box or any other PC ecosystem hoping to find space in the living room is Apple, according to a lecture given by Valve co-founder Gabe Newell to a class at the University of Texas' LBJ School of Public Affairs. "The threat right now is that Apple has gained a huge amount of market share, and has a relatively obvious pathway towards entering the living room with their platform," Newell said. "I think that there's a scenario where we see sort of a dumbed down living room platform emerging — I think Apple rolls the console guys really easily. The question is can we make enough progress in the PC space to establish ourselves there, and also figure out better ways of addressing mobile before Apple takes over the living room?... We're happy to do it if nobody else will do it, mainly because everybody else will pile on, and people will have a lot of choices, but they'll have those characteristics. They'll say, 'Well, I could buy a console, which assumes I'll re-buy all my content, have a completely different video system, and, oh, I have a completely different group of friends, apparently. Or I can just extend everything I love about the PC and the internet into the living room.'... I think the biggest challenge is that Apple moves on the living room before the PC industry sort of gets its act together."
